Which Doctor Who Companion Are You?

You are spunky, determined, and as religiously devoted to your Doctor as you are to chips. (He's the only one who doesn't know how sweet you are on him, too.) You never stay put when you're told to stay put, but just when everyone expects you to get roasted by the monster of the week, you turn right around and figure out the mystery. You're sharp as a tack, but also sensitive, knowing when the Doctor needs someone to back him up or when he just needs a hand to hold. He seems to think he can get rid of you... you're quick to show him he's wrong!
